  • Question

  • What problem is solved by Dijkstra's banker's algorithm?


  • Options
  • A. mutual exclusion
  • B. deadlock recovery
  • C. deadlock avoidance
  • D. cache coherence
  • E. None of the above

  • Correct Answer
  • deadlock avoidance 

    Explanation
    The Banker's algorithm is a resource allocation & deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of pre-determined maximum possible amounts of all resources, and then makes a "safe-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.
